Belgium. Planning trip for 5 nites/Ghent Marriott and 5 nites at JW Marriott/Mayfair, London. Don't want a car and wondering how easy it was traveling by train to Brugge, Brussells, and to London. Also want to tour WWII sites-advice on priv tour?
Train travel is easy in Europe. Trains run frequently between Brussels and Ghent. This should help you: http://www.seat61.com/Belgium.htm The Ghent Marriott is great! Enjoy your trip. I would suggest staying a night or two in Brugge... it is so beautiful lit up at night when the day trippers are gone.
Traveling to Brugge from Brussels is appx 40 minutes. You can catch the train beneath the airport in Brussels and transfer at Centraal (maybe Midi) Station. When you transfer trains be sure to check the train car's destination. Belgian trains split and the first part of the train may go to a different destination than the back part. Brugge is a delight and is my favorite. We have also used trains to go to Antwerp, Mechelen and Oostende with no problems. Belgian trains are very easy to use and go most places. Another interesting town is Bouillon in the southern i.e. French, part of Belgium. Bouillon, on the peaceful Semois River, has a wonderful crusader's castle and the local church rings Song of Joy each morning. Bouillon is a walking city and has no need of a car. It's an easy day's trip from Bouillon to Orval Abbey (beer/cheese fame) and Bastogne (WWII) but I think you would need a car to see the sights at those locations.
Something NHM mentioned above reminded me that since Brugge is so easily accessible from Brussels, it is very crowded on weekends. Also, most museums are closed on Mondays. Best to spend time there Tues - Friday if possible.
